(AGO)j and the Signal Corps Historical Section. 

It would have been desirable , ideally, to have compared 
actual operations , item by item, with the Signal Annex reproduced as 
Chapter XI and the other annexes not reproduced in this document* 
For.- -such '-aw .imdertaking,. however s neither: d&i& nor-ttoe.:jmS: .sufficient. 

By way of assisting the interested student to do something 
of that sort himself, several diagrams illustrative of Seventh Amy 
communications have been furnished (in the Accomp&nying Appendices,) 
Those who care to pursue the matter further will find II Corps dia- 
grams in the records. of . the 53d -Signal- Battalion -and 24. Armored Divi- 
sion diagrams in those of the 142d Armored signal Company — available 
in both the AGO snd the Signal Corps Historical Section. For situa- 
tion naps and original overlays it is generally necessary to consult 
the divisional G-2 and G-3 records , also in the AGO files. 

Vthile this story stands by itself, he i«ho reads also MPart

c. There are often two exchanges in one town, one for long dis- 
tance and one for local calls* In some towns the long distance exchanges 
are in the main Post Office Building. 

d* Special units of the adUtla have been training in guarding the 
telephone and telegraph systems. It can be assueaed that "these., guards : are 
alao trained in the destruction of the equipment so that extensive damage 
; caa be : anticipated*

In i>ieily there is an additional obstacle to a highly developed hydro- 
electric system, in that many of the island 1 a rivers are neither power- 
ful nor accessible 'enough, for building vjork to be other than a long 
and costly undertaking* Both in 1937 and 193$ the six important hydro- 
electric plants produced 70 - 75 million KWH, or about 35 percent of 
the island's total power production* 

2. , In order to regulate the aupply of electric po.ver through- 
out the year, a considerable output froia thermal- stations is required 
from June until November, (inclusive)* Of the six principal t hernial 
generating stations in Sicily, several are relatively small capacity, 
but they are inqportant for peaJk-load operations and for the local power 
supplies. The output from, thermal stations was between 115 and 140 
million KWH in 1937 - 1938; this gives a plant factor of about 3000 
hours per year* Before Italy 1 s entrance into the war in 1940, the 
coal for Sicily* s thermal plant s was imported from Great Britain, Ger- 
many or Poland, "iow it presumably corses exclusively from Sardinia.

which were unsatisfactory in themselves and interfered considerably :

ffos jrsessage canter for the landing operation opened on the 
Bisoayne on 6 July and operated continuously until the 16th. The 
Advance CP opened ashore behind w Beaeh Tellow H at 1232, D-day, es- 
tablishing as quickly as possible wire lines to the infantry regiments, 
radio station® in the nets in operation afloat, and a message center* 
The message center was seldom used for tactical Messages from Division 
to lower units, however, since staff officers generally coaiaunicated 
with subordinate cotamanders by direct voice radio, ft*® laain CP was 
'set up. at 1535, D-day, on the north side of tdcata, with radio, wire, 
and messenger service to divisional and attached units, « J« and "T» 
service ashore was begun at 1000 the next day with the aid of a 
detaeJwnt of the 128th S%ial Badio Intelligence Company, and by

at the CP.

more ; carefully fcriaul at sd and coordinated* 

•Loading »■ The landings were successful partly because the proper pri- 
orities had been established, the 1st Signal Company, for example, 
attached fully equipped radio and wire teams to each Combat Teg®, and 
divided the remaining men and equipment between the Division CP and 
alternate CP, In the case of units split into assault and follow-up 
echelons, however, some observers found a loss of efficiency inherent 
in the arrangement that ims not worth "the few advantages.^ 

Hor was the preparation of supplies entirely satisfactory. 
Although the Ariay Signal Supply Officer indicated on the requisitions 
which items were to be given special packing to withstand possible 
iiaaersion in salt water and rough handling over beaches, the job was 
not done well enough in all instances to prevent damage* It was 
recommended that, in the future, a tactical signal officer with experi- 
ence in beach' landings supervise "enough of the packing, in the begin- 
ning to assure himself that the base section is doing it properly

possible to turn out only one such vessel by 24 April, Consequently , 
all the others used to invade Sicily were improvised , and much the saras ' 
problems were encountered as in operation "TORCH". It was therefore 
believed that more radio set 3 and code machines were necessary; that 
temporary radio installations on deck were unsatisfactory, that each 
radio set should -be put in by an expert and served, by 'three* operators,, 
and that these tien. should be the best available • There was no doubt 
about the necessity for separate- channels for each major service! an Air 
Fore© observer advised furnishing the 'Air Force with a completely sepa- 
rate message center*. More space was essential— for both men and equip- 
ment • Largely for that reason it seemed vital that more true head-

Training of the division staffs themselves in. the 
amphibious phase was neglected* During the final full 
scale division landing exercise the staffs of at least 
two of the three assault divisions were either ashore 
to watch their troops land or were on board without 
using the division channels of communication « It is 
an excellent practice to observe the assault troops' 
closely ^ of course, but at least one full scale exer- 
cise should have been held with the staff directing the 
exercise from the ships by the use of the ships'- commu- 
nications* 

The installations on board a- headquarters ship are 
more complicated and involved than the staff realise; 
before they use it for the first .ti&e, and Comoand. 
Post exercises with the entire staff aboard should be 
held with real or simulated channels to higher and 
lower headquarters, « * • 



Supply Operations. 1? s 220 tons of signal equipment were used in the 
Sicilian campaign—about one-sixth of the weight of all . supplies* T/BA 
equipment - v*as "approximately complete % and for the most part the 
front received .what it needed* But there were important shortages—, 
notably field wire anci dry cells. The 3d Division made ends meet only 
by applying intensive salvage measures and, on one occasion . by send- 
ing a truck on a 200 nile round trip to the nearest source of wire. 
The 1st Division once had to retreat with heavy losses for lack of 
¥-130 to contact the artillery * Another difficulty was the replace-* 
ment of battle losses in radio sets; they were generally deficient
